We've seen a lot of horror films, so if we were Famke Janssen, we'd be very scared right now.

The Wolverine and X Men star (she plays Jean Grey) will probably be checking under the bed tonight after someone committed the creepiest crime ever - breaking into her house to leave a spooky gift.

According to TMZ, the actress came home to her apartment in New York to find a children's book - The Lonely Doll - in the middle of her bed. She reportedly freaked out (understandable) as she doesn't own the book, and called the police.

The worst part of the whole story is that sources tell TMZ that there's no sign of forced entry into the house, and she told police that no-one else has a key. It's as if ... the book appeared ON IT'S OWN. Creepy.

It's all about two toys that promise to never, ever leave each other (horrible) and it's even got a toy doll on the front. Oh dear. Police are reportedly treating it as a burglary (although it doesn't sound as if anything else was taken) and are checking surveillance footage.

Famke hasn't commented yet - she's probably a bit scared.

If you're all "where have I seen her before" - she's actually quite famous. She's been in everything from X Men to Taken 2 to Nip/Tuck. She's also been in loads of scary stuff - The Faculty, House On Haunted Hill and this year's Netflix series Hemlock Grove. So she should be a bit braver than us.

She wouldn't be the first celeb to have a weird stalker - Taylor Swift's security stopped a man swimming towards her house at 2am in May, and last year Miley Cyrus's stalker was sent to prison after being arrested in her garden with a pair of scissors. Stay safe, Famke!
